November 1980. Prepared by Ohio River Basin Energy Study (ORBES). Grant no. EPA R805585.. Central Ohio is an area where the long range transport of air pollutants is a problem, and a relatively small increase in pollution emitted from sources within the standard metropolitan statistical area (SMSA) could cause the area to violate federal primary standards for sulfur doxide and particulates. The potential loss in economic product to the Columbus SMSA is estimated by calculating the difference in economic output between the projected increase in potential output possible under existing air quality regulations without additional background pollution from new out of area fossil fuel power plants, and the projected increased in output possible when this additional source of pollution is taken into account. Estimated losses are provided for seven different ORBES scenarios. Includes bibliographical references.
